yea def. swap out the plugs. do you know if u got fuel? -Spark, Fuel, Comp.- thats what u need for ur car to start...if u got the spark, check for the other two. when you get your plugs tomarow i would sujest in gettin a Compression tester. its a great tool to have. good way to test future cars that you might buy, to check the engine and see how worn it is. its not too expensive.. i think like 30bux ish at advanced auto...
